Figure 3. — Contrast recovery for different spheres in the Abdo-Man phantom. The plotted data are mean values from three repeated acquisitions. The error bars on each data point represent standard errors on the mean. (a) Results for the sphere with a solid core. (b) Results for the four hot spheres. In almost all cases, contrast recoveries for no motion are significantly greater than those for motion with respiratory gating [data-driven (DDG) or externally driven (RPM)], which are greater than those for motion without gating (all p < 0.05). DDG, data-driven gating; RPM, Real-time Position Management system.
